Abstract:
PROBLEM TO BE SOLVED: To provide an efficient frame structure for wireless communication.SOLUTION: A wireless communication system comprises first and second air interfaces based, e.g., on macrocells and femtocells, and is configured to: frequency division multiplex (FDM) the first and second air interfaces in a downlink subframe of a frame; and time division multiplex (TDM) the first and second air interfaces in an uplink subframe of the frame.
Abstract:
CONFUSION RESULTING FROM ASSIGNING THE SAME NODE IDENTIFIER TO MULTIPLE NODES IS RESOLVED THROUGH THE USE OF CONFUSION DETECTION TECHNIQUES AND THE USE OF UNIQUE IDENTIFIERS FOR THE NODES. IN SOME ASPECTS AN ACCESS POINT AND/OR AN ACCESS TERMINAL MAY PERFORM OPERATIONS RELATING TO DETECTING CONFUSION AND/OR PROVIDING A UNIQUE IDENTIFIER TO RESOLVE CONFUSION.
